Nondisp fx of unsp tibial tuberosity, 7thM

This code describes a fracture of the tibial tuberosity that is not displaced, meaning the bone fragments are still in their normal alignment. It specifically indicates that the fracture is an open fracture of type I or II (meaning the skin was broken, exposing the bone) and has failed to heal properly, resulting in a nonunion. This is for a patient who is receiving follow-up care for this specific injury.

This code is used when a patient presents for ongoing treatment of a previously diagnosed nondisplaced, open type I or II fracture of the unspecified tibial tuberosity that has not healed. This would include scenarios such as continued cast changes, physical therapy, or surgical planning for nonunion repair. It is appropriate for any encounter after the initial treatment of the fracture.

• Ensure documentation clearly specifies "nondisplaced" and "unspecified tibial tuberosity."
• Verify the open fracture type (I or II) and the presence of nonunion are explicitly stated.
• Confirm this is a subsequent encounter, not the initial treatment of the fracture.
